Ann: Separate Commercial Grade Concentrates - Kempfield Milestone, page-2

SIGNFICANT KEMPFIELD MILESTONE ACHIEVED
SEPARATE COMMERCIAL GRADE ZINC AND LEAD CONCENTRATES PRODUCED
SUBSTANTIAL BOOST TO PROJECT ECONOMICS
Highlights:
■ High quality commercial grade separate concentrates achieved: zinc (54-59%), and lead
(47-64%).
■ Excellent zinc recoveries: 87-92% - the dominant base metal of the deposit.
■ High combined recoveries for silver (75-85%) and gold (66-90%).
■ Kempfield repositioned as an economically viable polymetallic project with zinc, silver, lead
and gold revenue streams from separate saleable zinc and lead concentrates.
■ Industry standard flotation process design for potentially favourable capex and opex.
■ Drilling to proceed as the top priority.
